This invention relates to winding machines and particularly to a machinefor winding or spooling wire and other attenuated materials.

One obj ect of the invention is to provide a winding machine wherein thespool or other receiver on which the material is wound is rotated from adrum or drive-roll whereby the rate of draft on the strand materialremains constant from start to finish of the winding.

Another object of the invention is to provide a .winding machine havingmeans for.

, or other receiver on which the material is wound through theintermediary of gearing adapted to be altered in ratio to provide forthe proper disposition of the turns of the winding in accordance withthe thickness or diameter of the material being wound.

Another object of the invention is to provide a winding machine ofsimple cnstruction, capable of operation at high speeds-to effectmaximum production, with its mechanism proof against derangement orgetting out of order and durable in use over long periods.-

Further objects of the improvement are set forth in the followingspecification which describes a preferred form of construction of theinvention by way of example as illustrated by the accompanying drawings.

Fig. 4 is a side view of the machine looking in the direction oppositeto that of Fig. 2 and showing the gear-casing in section.

In the present embodiment of the invention the winding machine isshownas adapted for winding wire on spools, but it is to be understoodthat it may be employed for winding other kinds of material anddifferent types of packages.

As shown in Figs. 1 and 2, the winding mechanism is mounted on a frame 2comprising a base 3 adapted to be bolted to a table,- bench or othersupport and having upright side-members 4 which carry the bearings forthe various shafts of the machine. The sidemembers 4 may be constructedin the form of posts or stanchions 5, 6 and 7 arranged in oppositerelationatthe sides of the base and connected by web-like ribs 8. Theforward stanchions 5 carry the traverse-mechanism, the rearwardstanchions 7 serve as a' support for the frame in which thewinding-spindle is j ournaled, and the central stanchions 6' areprovided with bearings for the drive-shaft 10 which carries the frictiondrive-roll or drum 11. As shown more particularly in Figs. 1 and 3, thedrive-shaft 10 is journaled in bearings 9 at the top of the posts 6 andextends beyond the side of the machine to adapt it to be connected to,drive other units if desired. On its right-hand end, as Viewed in Fig.1, is a suitable-belt-pulley 12 keyed rotatively therewith at 13 andsecured inplace by a set-screw 14:. The hub of the pulley 12 abutsthe'side of one of the bearings 9, and a collar 15 on the outside of theopposite bearingis secured to the shaft .10 by means-of a set-screw 16to prevent longitudinal movement of the shaft.

The friction drive-roll or drum 11, shown in part sectional view in Fig.3, is mounted on the shaft 10 midway between the bearings 9, beingsecured rotatively with the shaft by means of a key 18 and fastened inplace by a set-screw 19 in its hub. Preferably, the roll 1 or drum 11has a covering 20 of suitable resilient material such as leather orfiber on its periphery which is held in place by counterm 4 sunk screws21. The drive-roll or drum 11 is driven directly from the pulley 12which may be belted to a suitable source of power, for example, aline-shaft or an electric motor. The drive-roll or drum ll'is adapted tobear against the barrels of a spool S on which the winding is performedor to contact with any other suitable form of core or receiver to rotatethe latter. As herein shown, the spool S is carried on a winding-spindlewhich is rotatably journaled in bearings on a swinging frame 26. Asillustrated in Fig. 3, the frame 26 is provided with an enlarged hub 27,the ends of which are counter-bored to receive a pair of outerball-races 28. A corresponding pair of inner ball-races 25) are held onthe shank 30 of the winding-spindle 25 between a flange 31 at one endand a washer 32 at the other end. The races 28 and 29 are of usual formadapted to receive balls 33 which revolve therebetween, thus providingan anti-friction bearing for the w ndingspindle.

The spool S is .received on the projecting portion of the spindle 25 anda hand-nut 35 is screwed onto the threaded end of the spindle to hold itin place. Preferably, the nut 35 has a tapered or frusto-conical portion37 which cooperates with a similar tapered portion 38 on the flange 31to enter the ends of the bore of the spool S to center it on the spindleand secure it rotatively therewith.

The frame 26 carrying the winding-spindle 25 is rockably supported on across-shaft 40 which is journaled in suitable bearings at the top of theposts 7 at the rear of the frame 2. As shown more particularly in Fig.3, the frame 26 is provided at its rearward end with a forked portion oryoke 22 having hubs 23.

pivoted on the shaft 40. Referring to Fig. 2, the frame 26 is ofelbow-shape in side elevation, being provided with a rearwardlyextending arm or lever 24 shaped at its end to form a handle by means ofwhich the frame may be rocked upwardly to remove the spool from contactwith the driving-drum 10 when it is desired to arrest the windingoperation.

' A detent-lever or latch 42 pivoted at 43 to the side of the frame 2rests across the side of the yoke 22 of the frame 26 and is providedwith a step or shoulder 44 adapted to drop into engagement with the edgeof. the yoke when the frame 26 is raised into the posltion illustratedin Fig. 4. The lever 42 thus acts to sustain the frame 26 in raisedposition with the spool removed from contact with the driving-drum 11,the manual release of the lever permitting the frame to be lowered toreplace the spool'against t e drum.

Referring again to Fig. 3, one hub 23of the frame 26 is held against theside of the bearing on the post 7 by means of a collar 45, and a secondcollar 46 abuts the side of the oppositehub 23 of the frame. and 46 aresecured'fast to the shaft 40 by The collars means of set-screws 48 andthus serve'to prevent movement of the frame longitudinally of the shaft.

It has been stated that the winding-spindle 25 serves as the drivingmeans for the traversing-mechanism of the machine and for this purposeit is caused to drive the rearward shaft 40 through a train of gearingcarried on the side of the frame 26. The outer end of the shank 30 ofthe winding-spindle 25 is reduced in diameter to receive a spur-p111-ion'50 secured in place against the washer 32 which abuts the side ofthe outer ball-race 29 by means of a nut 5.2. The nut -52 is screwedonto the reduced threaded end of the shank 30 against a washer 53 andthe pinion is keyed to the shank at 54. The pinion 50 meshes with a gear55 which is carried on a stud 56 projecting through a hub 57 on theframe 26. The gear 55 is formed integral with 01' carries fast on itsside a gear 60, the two gears being keyed to the stud 56 at 61 andsecured in place by a nut 62 abutting a washer 63, it being understoodthat the stud 56 is arranged to rotate in its bearing in the hub 57 Thegear meshes with a gear 65 which, in the present form of construction,serves as a change gear adapted to be replaced by others of differentsize to vary the ratio of the gearing. The gear 65 is rotativelyjournaled on a stud 66 held fast in the end of the arm 67, see Fig. 4,which is attached to the side of the frame 26 by means of a bolt 68. Thebolt 68 extends through a slot 69 in the arm 67, thus rendering the armadjustable to adapt it to be set in different ositions in accordancewith the diameter 0 the change gears carried by the stud 66. The gear 65is rotatively connected with a gear 70 by means of a slotted collar 71arranged between the hubs of the gears which have lugs 72 engaging theslots in the sides of the collar. The gears 65 and 70 are held in placeon the stud 66 by means of a nut 73 and washer 74 abutting the side ofthe gear 70.

The gear 70, which also constitutes a change gear to be displaced byothers of differvent size, meshes with a driven gear 75 keyed to the endof the shaft 40' at 76 and secured in place by means of a nut 77 andwasher 78. It will be observed that through the train of gearing abovedescribed the shaft 40 is driven from the winding-spindle 25 at agreatly reduced rate of speed v which may be varied by substitutingother gears for the ehangegears 65 and 70. The shaft 40 is connected bygears 85 and 90 to drive an inclined shaft 80 which extends forwardly tothe front of the machine to adapt it to drive the traversing-mechanismto be later described. As shown most clearly in Figs. 2 and 4, therearward end of the shaft 80 is journaled in a bearing 81 on the side ofthe post 7 while its forward end turns in a bearing 82 projectingupwardly from the base 3 v thereto at 86 and held in place by a nut 87.

way may I bars or rods 107 held in ears 108 at the top The skew-gear 90meshes with the similar gear 85 keyed to the shaft 40 at 91.

The above described gearing is enclosed and protected by a casin 88arched over the top of the frame 26 an secured thereto by screws 89passing through suitable ears 92 on the side of the casing.

The forward end of the shaft 80 is provided with a worm 95, eithersecured fast thereon or formed integral therewith as il-' lustrated inthe present drawings. As shown most clearly in Figs. 1, 2 and 4, theworm 95 meshes with a worm-wheel 96 which is keyed fast to a cam-shaft97 journaled in bearings in the posts 5. The shaft 97 carries 'acylindrical cam 100 having its periphery provided with-a helical groove101 which acts in the usual manner to impart reciprocation to atraversing-guide for the wire or other material to be wound. Asshown inFig. 1, the cam 100' is keyed to the shaft 97 at 102 and secured inplace by a set-screw'103. The

hub of the worm-wheel 96 is arranged be tween the end of the cam 100 andthe side of one of the bearings on the post 5, whereby it cooperateswith a collar 104 abutting the side of the bearing on the opposite post5, and secured to the shaft 97 by aset-screw 105, to hold the shaft fromaxial movement in its bearings.

'Thetraverse-guide for the wire or other material is reciprocated fromthe cam 100 and may be of any suitable construction. As herein shown itcomp-rises a carriage 106 adapted to slide on a trackway extendingbetween the two opposite posts 5. The trackconsist of two parallelhorizontal of the posts 5 by meansof set-screws 109. The carriage 106 isformed with a rearward portion 110 bored to receive-the rod 107 andforked bearings 111 straddling the forward rod 107. Projecting froma lug112- on the under-side of the carriage 106 isa pin or stud 113 carryinga bowl or roll 115 which engages the helical groove 101 in the cam 100.Rising from .one side of the carriage 106 is a post 116 provided with aninclined, interiorly-threaded hole for receiving a thumb-screw 117 whichis formed with atapered point 118.

Driven through a hole in the post 116 apin or rod 120 having itsopposite end held in a hole in an ear 119 at of the carriage 106;Mounted to slide on the pin 120 is a vertical arm121 provided with a hub122 surrounding the pin. The arm 121 has a forwardly extending leg 123which is forked at its end to adapt it to straddle the in Fig. 4, by

the opposite side ear 119. I The spring 126 tends. to hold the arm 121pressed against theconically pointed end 118 of the thumb-screw 117, andby turning the screw the arm may be adjusted one way or the other to setthe strand-guiding sheaves or wheels 125 in alinement with the end'flanges of the spool S after the latter has been placed on the spindle25.

In use the complete machine is operated as follows: The spool S, whichis usually provided with a relatively large barrel and narrowend-flanges or heads, is placed on the spindle 25 and the hand-nut 35screwed up against its end to clamp 'it in position with the taperedprojections 37 and 38 tightly engaging its bore. terial to be wound onthe spool is drawn off from its source of supply, carried around theperiphery of. the first guide-sheave 125,

thence down under the second sheave, whence it is led to the barrel ofthe spool S to which its end is fixedly attached. While the machine isbeing prepared for operation the frame 26 is held in raised position, asshown the engagement of the notched detent-lever 42 with the yoke 22 ofthe frame. It will be understood that the drive-shaft .10 carrying thepulley 12 is driven continuously from any suitable source of power.Therefore, to start the winding operation it is only necessary for theoperator to release the lever 42 and lower the frame 26 by means of thehandle 24 until the barrel of the spool comes into contact witli theperiphery of the drum 11, as shown in Fig. 2 of the drawings. The drum11 will then act to rotate the spool S through contact of its peripherywith the it-drives the winding-spindle 25 carrying the pinion 50 fast onits end. The pinion 50 turns th-e gear 55, and through the lattersconnected gear 60 drives the coupled changeears 65-and-70. The gear 70drives the gear to rotate the rearward shaft 40 and the skew-gearcarried on the opposite end thereof is caused to drive the gear torotate the inclined shaft 80. The worm on the inclined shaft 80 drivesthe worm-gear 96, which, in turn, drives the shaft 97 to rotate causesthe roll to travel in its groove 101 whereby the traverse-guide carriage106 The wire w or other ma Ill) the cam 100. The turning of the cam iscaused to be reciprocated back and forth on its tracks 107. Thereciprocation of the traverse-guide causes the strand 'w of wire orother material passing over the guide-wheels 125 to be traversed axiallyof the spool S whereby to deposit it in helical turns disposed inadjacent relation between the end flanges of the spool.

It has been explained that the arm 121 carrying the guide-wheels 125 maybe adjusted laterally on the carriage 106, this ad justment beingperformed when the spool S is first placed on the Winding-spindle 25.The spools S may vary somewhat as regards the size of their bores, anddue to this they may not always assume the same position longitudinallyof the spindle when the hand-nut is tightened against their ends.Therefore, to insure that the traverse of the guide-wheels 125 mayregister with the space between the heads of the spool S the position ofthe arm 121 carrying the wheels is shifted one way or the other asrequired by simply turning the adjusting-screw 117.

As the machine winds the wire or other material onto the barrel of thespool S it will be deposited in overlying layers of closely spacedhelical coils, and as the diameter of the wound mass increases it willcause the frame 26 to be swung upwardly to accommodate the growth in thewinding. When the spool is filled the frame 26 is lifted by means of thehandle 24 to remove the surface of the wound material from contact withthe drive-roll 11 to arrest the winding operation.

As the frame 26 is rocked upwardly the detent shoulder 44 on the lever42 will engage across the edge of the yoke 22, and thereupon the framewill be held in its elevated position until it is desired to start thewinding of a new spool.

It'will be observed from the foregoing that the present inventionprovides a particularly simple and and efficient machine for Windingwire and other materials onto spools or for packaging the same in otherforms.

It is to be particularly noted that the spool or other receiver for thematerial is driven from a constantly rotating drum through the contactof the winding with its periphery. It will therefore be understood thatas the wound mass increases in diameter the speed. of rotation of thespool will decrease, but on the other hand the lineal speed of draftonthe material will remain constant.

As the rotative speed of the spool is decreased it is necessary that therate of movement of the traversing-means for the wire be correspondinglyreduced and this is accomplished by reason of the fact that thetraversing-mechanism or reciprocating-means for the traverse-guide isdriven directly from the winding-spindle; Through this arrangement ofthe mechanism the rate of traverse of the guide is regulated to depositthe coils of winding in predetermined relation to lay the material onthe spool in smooth, even layers with a uniform spacing of the turns orcoils of winding therein. It will further be seen that the speed oftraverse of the guide may be adjusted in ratio with the speed ofrotationof the spool in accordance with the diameter or thickness of thewire or other material being wound. This adjustment is I readilyaccomplished by substituting gears of different diameter for the changegears and 70. In changing the gears 65 and it is only necessary toremove the nut. 7 from the end of the stud 66, and in substituting othergears therefor their hubs are connected by the collar 71 and the arm 67is adjusted to position to' bring the gears into mesh by means of thebolt 68 extending through the slot 69 in the arm.

The present improved machine is especial ly simple in design and sturdyin construction to render it durable in use over long periods. It isparticularly to be noted that the machine requires no clutches or othermanually-operated drive-control and thus its operating parts are reducedto the minimum. The improved machine operates with greater efiiciency toproduce spools, packages or coils of Wire and other materials at highspeed to render it capable of maximum productivity.

While the present specification and drawings illustrate a preferred formof construction of the improved winding or spooling' machine, it is tobe understood that Various modifications may be made in the design andarrangement of the parts without departing from the spirit or scope ofthe invention.
